BUILDING ARCH CONSTRUCTION Filed Aug. 9, 1955 INVENTOR MICHAEL G. VAss Patented June 18, 193 5 nmpma ARCH CONSTRUCTION Michael G. Vass, Maywood, 111., asslgnor to United States Gypsum Company, Chicago, 111., a corporation of Illinois Application August 9,

6 Claims.

This invention relates to building constructions, and has reference more particularly to arches for use in doorways, windows, or other similar openings in a building.

An object of this invention is to provide an arch construction which is adapted to fit framework of any thickness.

Another object of the invention is to provide an arch construction having wings of expanded or other types of reticulated metal, which is attached to the framework of a building and forms a firm bond for a plaster coating.

A further object of the invention is to provide an arch construction in which the component parts may be shipped in knocked-down condition with a minimum of space required and then assembled on the Job easily and quickly; also to improve arch constructions in other respects hereinafter specified and claimed.

Reference is to be had to the accompanyingdrawing forming a part of this specification, in which:-

Fig. l is a perspective view of a doorway in a building with parts broken away to show the construction of the arch,

Fig. 2 is a perspective view on an enlarged scale, showing my improved arch member,

Fig. 3 is an elevation showing the manner of attaching expanded wings to the corner bead elements used in the improved arch,

Fig. 4 is a perspective View of a section of the corner bead with a modified form of attaching lugs for connecting the expanded metal part of the arch, and

Fig. 5 is a sectional view through a modified form 01 arch.

The arch construction consists of corner bead having a tubular nose or plaster ground it, and outstanding wings it and i2, preferably made of sheet metal rolled into form. Lugs i3 and it are struck from the wings i i and i2, respectively, for the purpose of quickly attaching expanded metal to the corner bead wings. Wings it of expanded metal have one edge shaped to fit the contour of the arched corner bead, and the other edges are secured to building framework 06 by any suitable means such as nails W. In assembling the wings it on the corner bead wings H, the lugs or prongs it are caused to extend through the expanded metal and are then bent over to engage the strands of the expanded metal.

The arch is composed of two spaced pairs of corner beads, as seen in Fig. 2, and the two pairs of corner bead are connected by strips it of expanded metal. The prongs B3 are attached to 1933, Serial No. 684,416

the strip IS in the same manner as heretofore described for the prongs H. In view of the fact that the thickness of the frame member I may vary from job to job, it is often found convenient to cut the strip l9 at the job from a larger sheet of expanded metal so as to produce the proper spacing between the arched comer bead. However, all parts of the arch may be shipped knocked down since the thickness of the frame member I6 is generally standard. Prongs or lugs l9 l3 preferably extend inwardly of flange ll of the bead so as to permit attachment of expanded metal wings Hi to the inside of the corner head, while prongs or lugs H are formed to extend to the outside of flange l2 to permit attaching strip 1. I9 after nailing wings l5 with attached arched bead members in place.

The corner bead may be made and used in straight lengths, in the same manner as beads 2 l, which are shown in Fig. 1, and which extend down .9 the corners of the doorway below the arch. The corner beads 2i may also be provided with prongs it for engaging expanded metal lath 22 which serves as a base for the support of plaster 23 or other cementitious materials. Plaster M is also applied to the expanded metal strip t9, the tubular beads iii serving as a plastering ground. Pointed rods 25 may extend into the tubular head it] and into the corresponding comer bead nosing it to connect the arch to the corner bead 28. at

In the modified form of construction shown in Fig. 4, cuts or slits 26 are formed in the edges of corner bead wings H0, and We so as to provide I prongs 2i for engaging the expanded metal used in the arch construction. This form of prong w is sometimes preferred to that shown in the preceding figures as being easier to make and somewhat easier to manipulate during erection of the arches at the job.

In the form of construction shown in Fig. 5, corrugations 29 are provided in the expanded metal 30 which connects the corner beads, these corrugations providing considerable flexibility to the body section of the arch thus permitting the workmen to expand or contract the arch within reasonable limits to accommodate any thickness of framework which might be used in a building.

I would state in conclusion that while the illustrated examples constitute practical embodiments of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:-

1. In an arch construction, a pair oi spaced corner beads formed into the desired shape 01' the arch, each of said comer beads having a tubular nose and a pair of outstanding wings formed at an angle to each other, lugs formed on said wings, and corrugated expanded metal engaged by said lugs and connecting said arched corner heads.

2. In an arch construction, a pair of spaced comer beads formed into the desired shape of the arch, each of said corner beads having a tubular nose and a pair of outstanding wings, lugs formed on said wings, a connecting member between said corner beads and engaged by said lugs, and wings of sheet material connected by said lugs to the remaining wings of corner head.

3. In a building construction, the combination with the framework of a doorway or other opening, 01. an arch composed of spaced corner beads having laterally extending wings, attaching members on said corner bead wings, wings of expanded metal secured to said framework and to the attaching means on said corner bead wings, and an arch member connecting the remaining wings of said corner head.

4. In an arch construction, a pair of winged corner beads in spaced relation, and corrugated reticulated metal connecting the wings of said corner beads and providing flexibility in said metal to flt building framework of diflerent thicknesses.

5. In an arch construction, substantially parallel, expanded metal wings and an arch-shaped strip 0t expanded metal extending between said wings, and corner beads including wings at substantially right angles to each other having lugs formed on the-wings thereof for engaging said expanded metal and securing the same together in a unitary arch construction.

6. In a building arch construction, a pair of arch-shaped, flanged corner bead members each having one flange disposed edgewise to the arc of the arch and the other flange disposed flatwise to said arc, integral attachment members on said flanges disposed to the inside of the comer bead on the edgewise flange and to the outside on the flatwise flange, perforated metal wings having one edge out to arch shape corresponding to the arch contour of the corner bead members and connected to the edgewise flanges by the attachment members thereon, and an archshaped strip of perforated metal connecting the flatwise flanges by means of the attaching members thereon, the whole assembly forming a metallic arch readily assembled on the job.
